Investigators believe that Harper was driving a Jeep SUV, with Rahmael Holt as his passenger, when Shaw tried to pull the vehicle over on Leishman Avenue at about 8 p.m. Friday, according to the criminal complaint.

Holt fled from the Jeep, and the vehicle left the scene, according to the complaint. Police said Shaw was shot and killed by Holt while chasing him on foot.

Harper was arrested Saturday at his home on Kenneth Avenue, and he told police that he had delivered marijuana to Holt before the traffic stop, according to the complaint.

Police said they found $2,500 cash on Harper, and two bundles of stamp bags of suspected heroin in a second-floor bedroom of the home, according to the complaint.

Rahmael Sal Holt

Police on Monday also questioned one of Holt's cousins as a person of interest. Although the woman was questioned at the New Kensington police station, she was not taken into custody and is not a suspect.

Holt, 29, of Natrona Heights, was arrested early Tuesday morning in the Hazelwood area of Pittsburgh. He was being held without bail in the Westmoreland County Prison after his arraignment by New Kensington District Judge Frank Pallone.
